The characterisation of the polysaccharide fraction II (PF II) in maize (Zea mays L.) roots by the yield, the content of monosaccharides, uronic acids, proteins, phenols, and the concentration of Cd²⁺. Different letters denote statistically significant differences in the parameters between the treatments at p < 0.05 according to the Tukey test
